Embodiment 1
[0017] An antistatic wear-resistant epoxy floor coating, made of the following raw materials in parts by weight: water-based bisphenol A epoxy resin 56, water-based UV resin 42, modified water-based polyurethane 15, calcium lignosulfonate 11, mica powder 7, hydroxypropyl methylcellulose 3, fumed silicon dioxide 1.5, negative ion powder 0.6, nano silver 0.3, water 10.
[0018] The modified water-based polyurethane is to heat the water-based polyurethane to 60°C, add an acrylic emulsion of 6% by weight of the water-based polyurethane, adjust the vacuum degree to -47kPa, stir in vacuum at 66r / min for 20min, continue to increase the temperature to 110°C, and then Add 6% of water-based polyurethane nano-titanium dioxide dispersion and continue vacuum stirring for 35 minutes, which can improve the film-forming and aging resistance of water-based polyurethane, shorten the curing time of epoxy floor, reduce the accumulation of dust, and improve the durability of epoxy floor. Gloss, pr...
